To all whom ntf1/)caty con/corra:y 1

` Be it known that we, `JAMES STOnnnn ROBERTSON and ROBERT B..RIcHAnDsON,

Jr., citizens of the vUnited States, residing at Paducah, the county of McCracken `and `State of Kentucky, have invented a new and useful Switch-Stand, ofwhich the followingy `is a specication.

The invention relates to improvements inI switch-stands. Y y. -The object 'offthe present invention is to improve the construction of switch-stands, morees ecially Vthe means/fior locking the switchever .tothe stand, and toprovide a.,.simple. and comparatively inexpensive switch-stand having means for permanently .locking the switch-lever in its customary position and for temporarilylocking the switchlever when \the 'switch is operated to run a` train on a siding or for any other purpose.

l- With these and other objects in view the.

invention consists in the construction `and novel' combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims. hereto appended, it being understood that various changes in the Jform, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages vof the invention.`

In fthe drawings,-. Figurev 1 is aside elevation of a switch-stand constructed in accordance with this invention, the switch-lever being :permanently locked. Fig.y 2 is va plan view o f the same. 3A is anenlarged sectional-view illustrating the construction of the lock for permanently locking the switchlever. Fig. 4-is a detail elevation, partlyin section, `illustrating theV construction of the latch for temporarily locking the switch-le- Fig. 5 is a detail front elevation ofthe I latch.

Like numerals of reference designate corresponding parts in all the igures of the drawings.

1 designates 4a switch-stand having a substantially circular base 2 and provided at its top with a substantially semicircular capplate 3, cast integral with the switch-stand and provided with intermediate and side notches 4 and 5, adappled to be enga ed by a switch-lever for loc g an arm 7 o? `a verti-- `IPVpatented*J'ul'y 3]., il

means. for connectingit with the movable i?" Y l switch-rails, is designed in practice' to .beo equipped at .its upper end witha suitable.' semaphoric device ,but thelatter may .be omitted. The arm 7, which is arranged upon f thek cap-plate 3, has .its oscillatory'movement limited y suitable stops 9, consistingof lugs; formed integral with. andproj ectingupwardx from the cap plate or portion 3 at opposite i sides thereoffi The 'outer portion 10fofth`e arm 7 isfslotted orbifurcated to receive'the switchi, .which is angularly bent, as shown, 57dl to cleara lock-casing 11 and'which is pro-,I vided atfits loweror outer end witha suitablel grip or handle 12; Theswitch-l'ever, which-l is providedwith a lock-engaged'iarm 13,' is adapted to be swung upwardiroin the .position illustrated in Figs'. 1, 3, 4and 4 to a' hori-f..

zontal position to kcarry it'out ofzengagement .L .i Y

withtheto .of the switch-stand, an whenf theswitchever is in the latter position itis adapted to be swungV horizontallyto operate 18o the switch. j M "1 y v The lock-casing, which is cast integral with the switch-standandwhich projects there-'V from in a Vvertical plan,`is providedwith ai. removable-:faceplate14, which is riveted or" otherwise secured .to the VbodyY portion of.n the casing.` The face-plate has a vsuitable key-" hole,`which isnormally coveredbyfa pivotf guard 15 for protecting :the locking mechanism. The frontorfoutere'dge of the lock-cas-V- ing is provided with asuitable entrance-open- `ing which communicates with its interiorfand throughwhich .the arm 13 is adapted .to eX- tend. The arm 13 which is integral with the switch-lever, is arrangedV substantially1 per.- pendicular to the latter, and it is provided in its upper edge with a recess forming 'a shoulated 1 catchJl7f; The: catchl, ,whichhis sub-L.v stantially quadrant-shaped, has a segmental extension and is mounted onasuitable pivot 18, which passes through a segmental eXtenv sion and Vwhich is spaced fromthe opposite edgesof the catch. The segmental extension is located at the to of the catch, and theopposite portions of t eupper edge of the same n JformA inner and outer shoulders. AThe inner shoulder is engaged by a vspring 19, and the l calshaft 8 rigid theiswitch-standf.. 5

outer shoulder engages a corresponding shoulder 20, formed by recessing the body portion of the lock and constituting a stop Jfor limiting the outward swing of the lower portion of the catch, whereby the switch-lever is locked against outward movement and is maintained in engagement with the top portion of the switch-stand. The spring, which is substantially U-shaped, has one side shorter than the other and is mounted in a suitable recess of the lock-casing, its free end engaging the inner shoulder of the pivot-catch. y The curved edge of the catch is arranged at the outer side facing the opening through which the arm 13 is introduced to enable the arm 13 to automatically lift the catch when the switch-lever is swung downward. As soon as the shoulder 16 passes the catch the latter is thrown downward by the spring 19, and the arm is thereby locked against outward movement. The catch is adapted to be operated by a suitable key to swing its lower portion inwardly and upwardly a sulicient distance to release the arm 13.

The lock is located beneath the intermediate notch of the top portion of the switch-stand for permanently locking the switch-lever, andthe latter is temporarily locked, when arranged in the position illustrated in Fig. 4 of the drawings, by means of a pivoted latch 21, consisting of a bar or piece provided at its outer end with a ball or enlargement 22 and having a perforation at its inner end to receive a pin 23 or other suitable pivot. The catch extends across a space or recess 24 of a latch-casing 25, which is substantially inverted-U shaped in cross-section and which extends outwardly from the switch-stand. The opening or space 24 is adapted to receive the arm 13, as clearly shown in Fig. 4, and.'

the latch-lever, which extends across the splace 24 and which is adapted to engage the s oulder 16 of the said arm, is mounted in a segmental extension 26, which projects from one of the walls of the latch-case. The latch-casing is provided with alined slots or openings to receive the latch 21, and the ball jecting outward from the switch-stand and having an opening arranged to receive the arm, and key-operated means mounted within the casing for engaging the arm to lock the switch-lever, said means including a quadrant-shaped catch having its curved side facing the opening through which the said arm is introduced.

2. The combination of a switch-stand provided with an integral exteriorly-projecting lock-casing, a pivotally-mounted switch-lever having an arm arranged to extend into the lock-casing, and a pivotally-mounted springactuated catch arranged within the casing and having its movement limited in one direction by the same, said catch being also arranged to swing into the path of the arm of therlever for loc ring the latter.

3. The combination of a switch-stand provided with a rigid exteriorly-projecting casing having an interior shoulder, a switchlever provided with an arm having a shoulder, a pivotally-mounted substantially quadrant-shaped catch located within the casing and arranged to swing into the path of the arm, said catch being provided with inner and outer shoulders, and a spring engaging one of such shoulders for holding the other shoulder in engagement with that of the casing.

4. The combination of a switch-stand provided with an exteriorly-projecting latchcasing having spaced sides, a switch-leven provided with an arm arranged to extend between the sides of the latchcase, and a weighted latch-lever disposed transversely of the casing in position for engaging the arm of the lever.

5. The combination of a switch-stand, an exteriorlyarranged substantially U-shaped latch-casing provided at opposite sides with alined openings, and having a lateral extension located at one of the openings, a latchlever extending through the said openings, and provided at one end with a weight and pivoted at its other end in the said extension, and a switch-lever provided with an arm for engagement with the latch-lever.

In testimony that we claim the foregoing as our own we have hereto ai'lixed our signatures in the presence of two witnesses.
